A cook has a scoop that measures ¼ cup. A bread recipe calls for 1 ¼ cups of sugar and 2 ½ cups of flour. The cook uses the scoop to measure and put both ingredients into a bowl. How many total scoops of both ingredients does the cook put into the bowl?

Answer :

Given:

A cook has a scoop that measures [tex]dfrac{1}{4}[/tex] cup.

Required sugar for bread recipe = [tex]1\dfrac{1}{4}[/tex] cups

Required flour for bread recipe = [tex]2\dfrac{1}{2}[/tex] cups

To find:

The total number of scoops of both ingredients does the cook put into the bowl.

Solution:

Required amount of sugar and flour for the bread recipe is

[tex]=1\dfrac{1}{4}+2\dfrac{1}{2}[/tex]

[tex]=\dfrac{1\times 4+1}{4}+\dfrac{2\times 2+1}{2}[/tex]

[tex]=\dfrac{4+1}{4}+\dfrac{4+1}{2}[/tex]

[tex]=\dfrac{5}{4}+\dfrac{5}{2}[/tex]

Taking LCM, we get

[tex]=\dfrac{5+10}{4}[/tex]

[tex]=\dfrac{15}{4}[/tex]

Now,

[tex]\text{Number of scoops}=\dfrac{\text{Total amount of sugar and flour}}{\dfrac{1}{4}}[/tex]

[tex]\text{Number of scoops}=\dfrac{\dfrac{15}{4}}{\dfrac{1}{4}}[/tex]

[tex]\text{Number of scoops}=\dfrac{15}{4}\times \dfrac{4}{1}[/tex]

[tex]\text{Number of scoops}=15[/tex]

Therefore, the required number of scoops is 15.
